Live in SD...
I live in San Diego and have gone down to mexico once. The guy that posted that you can flash a 20 to the cabby to take you to a reputable pharmacia is fulla shit. I have been with a buddy that only bought cytomel (T3) for 8 bucks. We got back in the cab and a few minutes later found ourselves in the backseat of a federali car. They took us to a back alley and extorted about 50 bucks from us. Moral of the story....the cabbies and the federalis are in Kahoots down there. I guarantee that the cabby notified the cops as we were going into the pharmacia cuz he knew we were comin out with something. It's NOT worth it to do it yourself...try and get it from a domestic source. If you are gonna go down there, have a buddy drive you to the border during the day and drop you off. You walk over, buy whatever gear you need for the week and inject in a bathroom down there and then walk back over. A little pricier (due to the 6dollar cab ride to Revolucion Blvd), but worth not gettin rolled on by the feddies. Also, your friend NOT parking on the US side and just waiting in the car for you will save you about 10bucks on parking each time. I only know of three guys that would go down to TJ with empty toilet paper rolls, buy their gear, stuff them in the rolls and tape them under their jocks (most cops and federalis are reluctant to pat down a man's groin). This way is cheaper than the once/twice a week trip, but you risk gettin rolled on at the border and if youre a pussy, you might have a heart attack waiting in that line when you cross over. Try and keep your cool. Really sweaty foreheads and armpits will you away. Good Luck fellas.
